Question

How to check if a point is inside a rectangle in Go

Answer 1

package main

import (
    "fmt"
)

type Point struct {
    x, y float64
}

type Rectangle struct {
    topLeft, bottomRight Point
}

func isPointInsideRectangle(p Point, rect Rectangle) bool {
    return p.x >= rect.topLeft.x && p.x <= rect.bottomRight.x &&
        p.y >= rect.topLeft.y && p.y <= rect.bottomRight.y
}

func main() {
    rect := Rectangle{
        topLeft:     Point{0.0, 0.0},
        bottomRight: Point{7.0, 7.0},
    }
    p := Point{3.0, 2.0}

    if isPointInsideRectangle(p, rect) {
        fmt.Println("The point is inside the rectangle.")
    } else {
        fmt.Println("The point is outside the rectangle.")
    }
}

package main

import (
	"fmt"
	"image"
)

func main() {
	// Define a rectangle using image.Rectangle
	rect := image.Rect(10, 10, 60, 60) // Rectangle from (10,10) to (60,60)

	// Define a point
	point := image.Point{30, 20}

	// Check if the point is inside the rectangle
	if point.In(rect) { 
		fmt.Println("The point is inside the rectangle.")
	} else {
		fmt.Println("The point is outside the rectangle.")
	}
}
